This hanging fragrance diffuser bottle is a small, empty 5 ml glass bottle designed for use with perfume, essential oil, or air freshener liquid. The mini bottle is intended as a decorative pendant for a car rearview mirror, window sill, or other suitable hanging spot, and it can also be used in bedrooms, closets, bathrooms, or offices. The bottle is made of glass with a cap and a hanging cord; the empty design allows you to choose your own fragrance and refill or change it when needed. To use, add a small amount of fragrance to the bottle, allow the cap to absorb the liquid, and hang the bottle in the desired location. The compact size is intended to add a subtle decorative touch without taking up much space. Because the bottle is empty, perfume or essential oil is not included, and users should avoid overfilling or hanging it in a position that could interfere with driving visibility. This item is suitable for people who enjoy customizable car fragrances and simple hanging decorations.
